Our team had the opportunity of receiving a tour of the Wastewater Treatment Plant in Lethbridge. This plant was built in the early 1900s and it is a biological nutrient facility, which makes it belong to the top five percent of all the treatment plants in the world. The plant removes phosphorus,nitrogen, ammonia, total suspended solids, biochemical oxygen demand (pollution), as well as works to reduces fecal and total coliform. The wastewater treatment plant is licensed under the Alberta Government which ensures that certain rules and obligations must be met. As previously mentioned, we had the opportunity to have a tour of the plant led by Duane Guzzi, the Process Coordinator of the wastewater treatment plant. During the tour we learned valuable information that would help us for the success of our project. As our project deals with the extraction of metals from tailings ponds, going to a wastewater treatment plant was beneficial as we learned the procedures and methods they take to remove chemicals from water and make it safe for rivers. </p>

INTERVIEWS

Dorothy Lok

We interviewed Dorothy Lok, who is a Municipal Approvals Engineer at Alberta Environment and Parks to explore the possibility of implementing our system into the Lethbridge Wastewater Treatment plant. Upon interviewing her, we learned that though our system is innovative, it would be unnecessary to implement it into the Lethbridge Wastewater Treatment plant as there is not a high concentration of metal ions in the wastewater. She also mentioned that the wastewater treatment plant already uses the metal-laden sludge produced as fertilizers for various crops. However, Dorothy Lok did propose that we should look into applying our system in other wastewater treatment plants of specific cities such as Flint, Michigan or industrial wastewater treatments plants, as these facilities contain a higher concentration of metal ions. In addition, she also suggested that the issue of mining and oil tailings ponds is a problem we could potentially tackle as tailings ponds contain a high concentration of metal ions that are detrimental to the environment. This would be more efficient for our system as the concentration of metal ions would be higher and therefore there would be more metal ions to remove. In terms of our system, Ms Lok told us, “You would really have to have a purpose for doing it [implementing our system in the wastewater treatment process]… whereas with tailings ponds, they need to be dealt with.” As a result of her advice, we pivoted our project goal to focus on the removal of metal ions from mining and oil tailings ponds rather than wastewater treatments plants. The successful implementation of our project could benefit communities locally and globally!


Senior Tailings Engineer for Alberta Energy Regulator

As mentioned, the environmental concern that tailings ponds cause is a crucial issue that many places around the world face, specifically Alberta. While our provincial economy relies heavily on the oil and gas industry, and we are very fortunate to have such natural resources at our disposal, these tailings must be monitored and dealt with cautiously. The Alberta Energy Regulator (AER) ensures the safe, efficient, orderly, and environmentally responsible development of oil, oil sands, natural gas, and coal resources over their entire life cycle. They aim to ensure the reclamation of tailings ponds and speaking with them helped us gain insight on many different aspects of our project.

A large concern for our project was using synthetic biology in an environment that is exposed to natural conditions; however, when discussing the issue of biocontainment with the AER representative, he advised us that biocontainment was not an issue whatsoever. This is due to the fact that tailings ponds do not support many living organisms aside from bacteria because they are so toxic (tailings ponds are relatively isolated environments). We also discussed and gained knowledge of the magnitude of tailings ponds, and were informed that they will continue to grow and must be taken care of.

We aim to resolve this concern using mathematical modelling until further experiments can be conducted. Our interview with the AER representative allowed us to verify that our project would be highly innovative and beneficial to both our economy and environment.


Professor Rood

In order to address our questions of biosecurity and feasibility, we had an interview with a biology professor at the University of Lethbridge, Dr Stewart Rood. We were told that our project required improvement in the applied design; tailings ponds are massive, and it would be very difficult to extract enough metals from them to make a profit. “My biggest problem with the system is scale,” informed Dr. Rood. As a result, in the final few weeks before the giant Jamboree, we researched other potential real-world applications of our system, in order to discover what it could be most effectively used for. We realized that although our system would not be extremely helpful in remediating tailings ponds samples, it would be beneficial to extract metals for profit from them -- but particularly in mining tailings. Moreover, we re-acknowledged the use of our system in wastewater treatment plants; although Lethbridge’s wastewater treatment plant would not require our system based on our tour, physical wastewater treatment plants used to clean the wastewater from industries discard large amounts of metals. Our system would definitely be purposeful there, in addition to places with metal contaminated water, such as Flint, Michigan. This demonstrates the improved knowledge we gained on the application of our project as a result of the advice given from Professor Rood.
